Linux MongoDB replica set cluster installation

The installation of Mongod in RS cluster is the same as a single machine, but the configuration file is slightly different,

Standalone installation path Linux under MongoDB 3.2.5 installation

The following is the RS cluster configuration file:

Systemlog:
Destination:file
Path:/home/mongodb/log1/mongod.log # #log的路径
Logappend:true
Storage
Journal
Enabled:true
DbPath:/home/mongodb/data # #数据的路径
Directoryperdb:true
Engine:wiredtiger
Wiredtiger:
Engineconfig:
Cachesizegb:6 # #这个值根据自己的机器的内存进行修改
Directoryforindexes:true
Collectionconfig:
Blockcompressor:zlib
Indexconfig:
Prefixcompression:true
Replication
oplogsizemb:10000
Replsetname:luo
Net
port:27018 # #根据自己的需要进行修改

Template of the configuration file I put a copy in the \\10.10.10.1\ShareDoc\User\luozhitao\replica set. Modify the next path and Replsetname.

After starting the Mongod instance on three machines, configure replica set, select any machine

./mongo 10.10.5.248:27018 After landing

> Use admin
Switched to DB admin

{_id:2,host: "10.10.5.248:27017", priority:800, Arbiteronly:true}
]
}
